Referring now to the drawings, the nuiiieral 1 designates a door embodying my invention having an inverted U-shaped frame 2 and the inner and outer sheet metal panels 3 and 4 respectively. As shown, the upright members 5 and 6 respectively of the frame constitute door pillars and are preferably provided at their inner and outer edges with the rearwardly and forwardly extending lateral flanges 7 and 8. The forward pillar 5 is preferably wider than the rear pillar 6',

` however the forwardly extending flange 8 of the rear pillar is preferably provided for a portion of its length with a lateral Hange 9 Serial No. 37,323.

which projects inwardly and terminates in substantial alignment with the rearwardly projecting flange 8 of the forward pillar 5. The cross bar 10 of the frame 2 constitutes a reinforcing member and is preferably channelsshaped. Any suitable means may be ein ployed for securing this bar 10 to the pillars 5 and 6 respectively. As shown, the outer base portion 11 of the channel bar is provided at its opposite ends with inwardly extendingvided adjacent to its lower end with a suitable:

opening 14 to permit access to the space between the panels 3 and 4 respectively. To provide a rigid construction. the inner panel 3 is preferably welded at its forward edge to the inner face of the rearwardly extending Harige 8 of the forward pillar 5 and is provided at its rear edge with an outwardlv extending flange 15 that is preferably welded to the outer face of the lateral flange portion 9 of the rear pillar 6. This inner panel 3 is also provided at its upper and lower edges with the outwardlv extending flanges 16 and 17 respectively. The lower Harige 17 is preferablv wider than the upper Hange 16 and terminates at its outer edge in a depending Hange 19. Thus. this depending flange 19 cooperates with the forwardly and rearwardly extending Hanges of the pillars 5 and 6 to forni an attaching frame for the outer panelv 4. As shown. this outer panel 4 is preferably provided at its side edges with flanges 20 which are return bent around and welded to the Harige 7 of the pillars 5 and 6, and is provided at its lower edge with a Harige 21 that is return bent around and welded to the depending flange 19 of the inner panel 3. The outer panel 4 is also preferably provided at its upper edge with a narrow Harige 22 that extends between the pillars 5 and 6 i so and projects inwardly over the upper flange 23 of the channel cross bar 10.

As shown, the outer panel 4 is preferably provided at the top, and side edges of the opening 13 with inwardly extending flanges il-l and 2G ref -cpectively which cooperate with the flange 16 to form a neat appearance around the window opening 13. As shown, the upper flange 24 constitutes the window header finish strip and conceals the lower flange 27 of the channel cross bar 10, while the lower flange 16 constitutes the window sill and preferably provided at its inner edge with a return bent portion 23 that terminates in a depending flange 29. The side flanges 2G are parallel to the pillars 5 and G respectively and are preferably provided at their inner edges with forwardly and rearwardly lateral offset L-shaped extensions 30 which cooperate with the rearwardly and forwardly extending flange S of the pillars 5 and G to forni channel-shaped runways for a vertically movable glass panel 31. To provide a strong and durable construction, the bases 32 of the extensions 30 are welded to the inner faces of suitable reinforcing st ips 33 extending longitudinally of the pillars. As shown, these strips 33 are parallel to the pillars 5 and G respectively and are provided at their inner edges from the upperedge of the inner panel 3 to the cross bar 1() with lateral flanges 34 and 35 respectively that are welded to the flange 8 of the pillars 5 and 6. To facilitate this welding operation, the strips 33 and the bases 32 of the extensions 30 are provided with registering slots 36 and 37 respectively for receiving suitable welding apparatus (not shown). Below the window opening 13, the reinforcing strips 33 have channelshaped portions 38 which are in alignment with the extensions 30 and are dapted to receive the window panel 31 when in lowered position. This window panel 31 may be raised or lowered by any suitable window control mechanism 40 mounted on the inner panel 3 and preferably travels in felt channels 41 which are preferably secured at their upper ends to the strip 33 and are secured at their lower ends in the channel-shaped portions 38 of said strips. Any resilient strip 42 may be secured to the depending flange 29 of the flange 16 to form a weather tight joint with the window panel 31, while a suitable resilient buffer 4A- for the lower edge of the glass panel 31 is preferably located at the bottom of the door. This buffer 44 may be any suitable construction but preferably comprises a rubber block l5 having a flanged base 46 that is held by a suitable bracket 47. As shown, this bracket is preferably formed of sheet metal and has a channel-shaj'ied npright portion 43. The sides of this upright portion are preferably provided at their cpposite ends with lateral :flanges i9 and 50 respectively, while the bachr 51 of the channel is preferably provided at its upper end with an inwardly extending flange 52. As shown, the lower flanges of the bracket sides are secured to the flange 1T of the inner panel 3, while the upper flanges 49 overlap the langes of the base 4G of the block l1-5 and hold the latter in position.

As shown in Figure 7 of the drawings, the flanges 22 and 24 respectively of the outer panel /1 terminate in line with the outer walls of the extensions 30, thus the glass window panel 31 may be readily inserted into or removed from the felt channels 41 by merely sliding the panel 31 past these flanges 22 and 24; respectively. Normally, the upper ends of the channels 41 are closed by a nietal header 54 which is detachably secured by suitable screws 55 between the flanges 22 and 23 respectively. As shown, this header 54 is substantially channel-shape in cross section and is provided at its lower edge throughout a portion of its length with a channel shape portion 5G which holds a suitable resilient channel-shaped strip 57 for receiving the upper edge of the glass panel 31 when in raised position. To facilitate attachment to the door, one wall 58 0f the channel portion 56 of the header has a lateral flange 59 that is adapted to fit between the lower flange 27 of the cross bar 10 and an upstanding flange GO at the inner edge of the panel 24 to position the header.

To provide a neat appearance the inner panel 3 of the door is preferably provided with a suitable cloth lining 61. As shown, this lining 61 is preferably provided with a backing sheet G2, preferably of card board, and is secured to the inner panel 3 by means of the fasteners 63 and finish strips G4; and 65 respectively. The fasteners 63 employed are preferably similar to those disclosed in my co-pending application, Serial No. 734,127 and are located at the lower edge of the inner panel 3, while the strips 64 and'fi respectively are preferably enameled or otherwise finished and are secured to the inner panel 3 at the side edges thereof. preferably by screws 66 which engage nuts 67 anchored in openings in the inner panel 3. The forward strip 64 conceals the joint between the inner panel 3 and flange 8 of the pillar 5 and is provided at its forward edge with an open return bent flange 68 that embraces the forward edge of the lining 61, while the rear strip G5 is mounted on the flange 15 of the inner panel 3 and is provided with the oppositely extending flanges 69 and 70 respectively. As shown, the flange (i9 projects rearwardly and conceals the joint between the flange 15 of the inner panel and the flange 8 of the pillar G, while the flange 70 projects forwardly in spaced relation to the inner face of the inner panel 3 and overlaps the rear edge of the lining 61,

Vhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.
